Probe into the Digital Watermark Anti-counterfeit Technology for Anti-arbitrary Rotation Attack

LIU Xu;School of Electronic and Electrical Engineering,Bengbu University;  
Digital watermarking technology can effectively store product copyright information. When it comes across tort or unauthorized communications, digital watermarking information can be extracted to verify the copyright information of product, which will effectively protect the integrity and security of copyright information, so digital watermarking technology has become the main technology in printing anti-counterfeit. Digital watermarking can embed product information into digital works, and it is widely used in the security anti-counterfeit work of digital video and printed publication. Before printing and in process of printing, digital manuscript has a certain probability of suffering from outside attacks, such as scaling, tilt, rotation, distortion and other similar image attacks, so it is in sore need of applying effective anti-counterfeit technology into product to effectively protect copyright information through digital watermark extraction. Therefore, this paper, centering on the digital watermark anti-counterfeit technology, comprehensively analyzes the digital watermark attack of anti-counterfeit printing and the characteristics of digital watermark, and systematically research anti-arbitrary rotation attack digital watermark printing anti-counterfeit technology based on wavelet transform to test algorithm robustness. Finally, solve all above problems scientifically.
